The invention relates to the field of wet gas purification technology and can be used in any industry, mainly in the energy sector.

The purpose of the invention is to eliminate the noted drawbacks in the developed device design.

In FIG. 1 shows a general view of a device for removing contaminants from gas flows (cross section); in FIG. 2 is the same, top view; in FIG. 3 is a variant of the device with an oblique cut of the tip; in FIG. L is a variant of the device with elastic threads; on the fig. 5 and 6 are a variant of the device, respectively, with spring elements and radial blades; in FIG. 7 - nozzle, top view.

The device for removing contaminants from gas flows (Fig. 1) comprises a chamber 1 made in the form of a body of revolution, with an inlet 2 and an outlet 3 for gas flow. An element for creating a curtain of washing liquid in the form of a hollow rotor 4 is placed inside the chamber 1, moreover, holes 6 are made in the bottom wall 5 of the rotor and a nozzle tip 7 is installed in its upper part. At the bottom of the chamber 1 there is an opening 8 for supplying an air flow. The rotor 4 is connected to an external energy source (not shown in FIG. 1), for example, by means of a flexible shaft 9. The inlet 10 for supplying the washing liquid is directed to the upper wall 11. of the rotor 4. The dirty washing liquid is collected in the collectors 12. Arrows 13 indicate the direction of the contaminated gas stream, and arrows 14 indicate the direction of movement of the air stream. The outer surface 15 of the nozzle tip 7 is provided with radial blades 16. The upper surface of the rotor is provided with elastic flexible elements in the form of threads 17 or a spring 18. The upper surface 19 of the housing has a direct generatrix, and the lower surface 20 is a generatrix in a concave line. ,

A top view of the device is shown in FIG. 3. Here, all designations are the same as in FIG. 1. Number 21 shows the direction of flow of the purified gas.

A device for removing contaminants from gas streams operates as follows. Contaminated gas is supplied to the chamber 1 through the inlet 2 in the direction of the arrows 13. Through the lower inlet 8, air is supplied under pressure in the direction of the arrow 14 and the rotor 4 is suspended on an air cushion. The rotor 4 is mechanically rotated from a foreign source by means of a flexible shaft 9

energy. As a source of mechanical energy, electric motors or internal combustion engines can be used. Through input 10 to the top

a portion of the rotor rotor 4 is supplied with flushing fluid. Rotor 4 sprays liquid upon rotation and forms a curtain of finely divided liquid particles. This liquid curtain is located across the flow of contaminated gas and provides for its purification. In addition, the air supplied through the opening 8 of the chamber 1 partially through the holes 6 enters the inner cavity of the rotor 4 and, under the action of centrifugal forces and air pressure, enters the nozzle tip 7 (Fig. 1). The air leaving the nozzle tip 7 will contribute to the turbulence of the gas flow, which will increase the contact of the contaminated gas with

0 particles of washing liquid and, accordingly, will increase the degree of gas purification. Contaminated flushing fluid is collected in the collectors 12, from where it enters the regeneration (not shown in Fig.). The purified gas is ejected in a tangential direction through the outlet 3. If the nozzle tip cut 22 is oblique (Fig. 3), then the air flow exiting through the nozzle will even more increase the turbulence of the gas flow in the chamber and the gas purification rate. Alternatively, if the flushing fluid is supplied to the nozzle tip provided with radial blades 16 from above, then

5, the intensity of the spraying of the washing liquid during the creation of the curtain is increased, thereby improving gas cleaning. Another design variant of the device comprises flexible elastic elements on the upper surface 19 of the rotor in the form of threads 17 or springs 18 (Figs. 4, 5). In this case, when the rotor rotates, centrifugal forces act on these elements, which change their position and stretch them, which increases

5 contact of the contaminated gas With the washing liquid and the time of this contact contribute to an improvement in the quality of gas cleaning.

Compared with the prototype, the rate of removal of contaminants from the gas stream is increased.

SUMMARY OF THE INVENTION 1. Device for removing contaminants from gas streams, containing a chamber in the form of a body of revolution, limited to the bottom

5 and the upper surfaces, an inlet and outlet for a gas stream, a drive element for creating a curtain of flushing liquid, placed across the gas stream in the chamber, a flushing fluid inlet directed to the surface of the element, and a collector

to collect contaminated liquid, it is noteworthy that, in order to simplify the design and increase the efficiency of removing contaminants in a wide range, the upper surface of the casing has a direct generatrix, and the lower one forms in the form a concave line and an air inlet, an element for creating a curtain of washing liquid is made in the form of a hollow rotor with upper and lower walls, the upper wall of the rotor provided with a nozzle tip, and the lower one made with openings in communication with the air inlet shnuju pillow.
